Lecture 5: fading & behavioural chaining psyb45. In the news 3 10 tips for sticking to your weight-loss plan. Video fading: rode the bicycle w/ physical help, and then gradually with fading, there was verbal cues to help the child ride the bike alone. Fading: the gradual change over successive trials of a stimulus that controls a response, so that the response eventually occurs to a partially changed or completely new stimulus. Once an error occurs, it tends to re-occur many times. Extinction (lack of reinforcement) can produce undesirable emotional reactions. Fading is not complete extinctionits shifts from stimulus to another fading can occur along different dimensions of stimuli (ex. volume of speech, content if speech, physical cues, environmental cues & etc) Stimulus discrimination training vs. fading: both are focused on establishing appropriate stimulus control over a certain behaviour, given that the target behaviour already occurs at least occasionally. Implementing fading effectively: careful consideration of the final desired stimulus.
